I have 2 ViewControllers and I create one UIImageView to show like Splash Screen on IPhone. I write it in TestAppDelegate.m :
====================
splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashScreen.image = [UIImage imageNamed:#"Default.png"];
[self.window addSubview:splashScreen];
sleep(6);
[splashScreen removeFromSuperview];
====================
My question is,
if I touch on this imageview I will go to 2nd ViewController.
else after time sleep, automatically to 1st ViewController.
So, it's possible to do that ?
Do this:
Add UIGestureRecognizerDelegate in appDelegate.h file.
#interface AppDelegate : UIResponder <UIApplicationDelegate,UIGestureRecognizerDelegate>
Now
splashScreen = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashScreen.userInteractionEnabled = YES;
splashScreen.image = [UIImage imageNamed:#"Default.png"];
UITapGestureRecognizer* tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleTap:)];
tapRecognizer.numberOfTapsRequired = 1;
tapRecognizer.numberOfTouchesRequired = 1;
tapRecognizer.delegate = self;
[splashScreen addGestureRecognizer:tapRecognizer];
[tapRecognizer release];
[self.window addSubview:splashScreen];
sleep(6);
[splashScreen removeFromSuperview];
//add ViewController1 here
ViewController1 *objViewController1 = [[ViewController1 alloc]initWithNibName:#"ViewController1" bundle:nil];
[self.window addSubview:objViewController1.view];
Now handler will be called when tapped on splash screen
- (void)handleTap:(UITapGestureRecognizer*)recognizer
{
// Do Your thing.
if (recognizer.state == UIGestureRecognizerStateEnded)
{
[splashScreen removeFromSuperview]; //edited here
ViewController2 *objViewController2 = [[ViewController2 alloc]initWithNibName:#"ViewController2" bundle:nil];
[self.window addSubview:objViewController2.view];
}
}
Yes. It's possible.In AppDelegate keep NSTimer.
In the selector of timer write code to push to the 1st view controller.
And put a Touch Recognizer on the imageview and on the touch event write code to push to the 2nd View Controller.

I'm going from storyboard to UISplitViewController in a xib. I want to logout of my storyboard view, which will bring me to the UISplitViewController. In the storyboard controller, I have a UITextField. I set it so that it doesn't dismiss itself after I press enter. However, it now stays open even when I switch to the splitviewcontroller, which I obviously don't want because i want to logout.
Logout Button
UIBarButtonItem *logoutButton = [[UIBarButtonItem alloc] initWithTitle:#"Log Out" style:UIBarButtonItemStylePlain target:self action:#selector(confirmLogout)];
Method to bring up UISplitViewCOntroller
- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex

} else {
[self.navigationController popViewControllerAnimated:YES];
}}
}
method gotoSplitViewController in the delegate:
-(void)gotoSplitViewController{

my UITextField
self.textBox = [[UITextField alloc] initWithFrame: CGRectMake(10, 660, 750, 90)];
self.textBox.backgroundColor = [UIColor colorWithRed:(209/255.0) green:(236/255.0) blue:(232/255.0) alpha:1];
self.textBox.returnKeyType = UIReturnKeySend;
self.textBox.delegate = self;
[self.view addSubview:self.textBox];
I've tried the resignFirstResponder if various places, including adding
- (void)viewWillDisappear:(BOOL)animated
{
[self.textBox resignFirstResponder];
}
However, none of them work. How do I get the keyboard to disappear after the views change?
I set
self.chatBox.delegate=nil;

I have used UITabbarController in my app.One of the tabBarItem is contactsViewController which displays list of contacts with UITableView.When I click on the tableRow it loads another view.then I click some other tabBarItem.again I click contactsViewController it takes me to the view where i left.It does not display default contact view.I have created UITabbarController progrmattically.How do i display default tabBarView on tabBarItem click?
tabbarController = [[UITabBarController alloc]init];
self.tabbarController.delegate = self;
tabbarView = [[UIView alloc]initWithFrame:CGRectMake(0, 431, 320, 49)];
UIImageView *tabImage = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 49)];
[tabImage setImage:[UIImage imageNamed:#"Taskbar.png"]];
[tabbarView addSubview:tabImage];
UIButton *tabItem1 = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 64, 49)];
[tabItem1 setImage:[UIImage imageNamed:#"Btn_Home.png"] forState:UIControlStateNormal];
[tabItem1 setTag:1];
[tabItem1 addTarget:self action:#selector(tabBarBtnAction:) forControlEvents:UIControlEventTouchUpInside];
[tabbarView addSubview:tabItem1];
-(IBAction)tabBarBtnAction:(id)sender
{
UIButton *btn = (UIButton *)sender;
// NSLog(#"tag %d\n",btn.tag);
[self resetTabBarBtnImage];
[self resetAllTabBarBtnImage];
PreviousBtnTag = btn.tag;
if ([btn tag]==1) {
tabbarView.hidden = YES;
[self.tabbarController setSelectedIndex:0];
[self.navigationController popToRootViewControllerAnimated:YES];
[btn setImage:[UIImage imageNamed:#"Btn_Home-Over.png"] forState:UIControlStateNormal];
}
else if([btn tag]==2)
{
tabbarView.hidden = NO;
[self.tabbarController setSelectedIndex:1];
[btn setImage:[UIImage imageNamed:#"Btn_Contacts-Over.png"] forState:UIControlStateNormal];
[self.navigationController popToRootViewControllerAnimated:YES];
}
In the appDelegate class , initially set the UItabbarController delegate as self
In the implememtation of appDelegate i.e .m file
//Assuming the first tab has the contactsviewController
-
(void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
if (tabBarController.selectedIndex == 0) {
UINavigationController *requiredNavigationController = [tabBarController.viewControllers objectAtIndex:0];
[requiredNavigationController popToRootViewControllerAnimated:YES];
}
}
I would recommend you to create the "tab bar controller" with the Interface Builder, as it is much easier to implement these kind of things this way. Anyway, if you want to keep trying to create it programmatically, try changing this:
[self.navigationController popToRootViewControllerAnimated:YES];
for this:
RootViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"Root"];
[self.navigationController pushViewController:controller animated:YES];
If this does not work for you, why don't you use Tool Bar Items, in instead of a Tab Bar Controller? It is quite easy to manage events with Tool Bar items, as they are treated like buttons.
Good luck!
I have a really strange UI glitch in my iPhone/iPad app. Because I wanted to find the cause of it, I created a new project with as little code as possible. The important code is below.
Basically, I have a UISplitViewController containing two UIViewController subclasses. When a button is tapped, the first one presents modally and as UIModalPresentationFormSheet a UIViewController subclass called Modal. In there, when a button is tapped, another UIViewController subclass called Text is presented, this time as UIModalPresentationFullScreen. In Text, there is a UITextView. When it is tapped, everything is alright, but when the iPad is rotated, I get this:
The white part is the Text view controller, the red part in the background is ViewControllerTwo.
Does anybody have any idea why this happens? And what I can do to fix it?
Here is the Project: MediaFire
Here is the relevant source code:
// AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
ViewControllerOne *one = [[ViewControllerOne alloc] init];
ViewControllerTwo *two = [[ViewControllerTwo alloc] init];
UISplitViewController *split = [[UISplitViewController alloc] init];
split.viewControllers = [NSArray arrayWithObjects:one, two, nil];
self.window.rootViewController = split;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
// ViewControllerOne.m
#import "Modal.h"
#implementation ViewControllerOne
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor blueColor];
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(30, 30, 44, 44);
[button addTarget:self action:#selector(buttonTapped) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
}
- (void)buttonTapped
{
Modal *modalOne = [[Modal alloc] init];
modalOne.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:modalOne animated:YES];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
// Modal.m
#import "Text.h"
#implementation Modal
- (void)viewDidLoad
{
[super viewDidLoad];
UIButton *buttonOne = [UIButton buttonWithType:UIButtonTypeRoundedRect];
buttonOne.frame = CGRectMake(30, 30, 44, 44);
buttonOne.tag = 1;
[buttonOne addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
UIButton *buttonTwo = [UIButton buttonWithType:UIButtonTypeRoundedRect];
buttonTwo.frame = CGRectMake(30, 100, 44, 44);
buttonTwo.tag = 2;
[buttonTwo addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:buttonOne];
[self.view addSubview:buttonTwo];
}
- (void)buttonTapped:(UIButton *)button
{
if (button.tag == 1)
{
Text *text = [[Text alloc] init];
text.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentModalViewController:text animated:YES];
}
else
{
[self dismissModalViewControllerAnimated:YES];
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
// Text.m
#implementation Text
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor greenColor];
UITextView *textView = [[UITextView alloc] initWithFrame:self.view.bounds];
textView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:textView];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
You may need to present the modal views from the UISplitViewController instead of it's subviews...
UISplitViewController *splitViewController = [(AppDelegate *)[[UIApplication sharedApplication] delegate] splitViewController];
[splitViewController presentModalViewController:modal animated:YES];
having difficulty getting UIButton Items to show.. I want to place several UIButtons within my UIPopUpController. I'm doing everything in a storyboard and I need to do this section programmatically.
- (void)showPopover:(id)sender
{
if(![popoverController isPopoverVisible])
{
myPopOver = [[PopUp alloc] init];
popoverController = [[UIPopoverController alloc] initWithContentViewController:myPopOver] ;
[popoverController setPopoverContentSize:CGSizeMake(300, 200.0f)];
permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
CGRect rect = (CGRect)[sender frame];
rect.origin.y = self.view.frame.size.height - rect.size.height;
[popoverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
else
{
[popoverController dismissPopoverAnimated:YES];
}
}
You could use a UINavigationController (it has already a navigation bar where you can attach buttons items) and add it as the content of your UIPopoverController. The UINavigationController can be istantiated using the initWithRootViewController method. In this case the controller would be your Popup class. For example, inside your showPopover method, you could do the following:
PopUp* myPopOver = [[PopUp alloc] init];
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:myPopOver];
popoverController = [[UIPopoverController alloc] initWithContentViewController:navController];
// do other stuff here to present you UIPopoverController
[myPopOver release];
[navController release];
Now, inside your PopUp class, within viewDidLoad method, you can customize the UINavigationController navigationBar. For example:
- (void)viewDidLoad {
[super viewDidLoad];
UIBarButtonItem *aButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Show" style:UIBarButtonItemStylePlain target:self action:#selector(somethingSelector:)];
self.navigationItem.rightBarButtonItem = aButtonItem;
[aButtonItem release];
}
where somethingSelector is like the following:
- (void)somethingSelector:(id)sender
{
// your custom actions
}
EDIT
Alternatively you can avoid to use the UINavigationController and create UIToolbar inside your PopUp class. Inside the UIToolbar you can attach UIBarButtonItems. See UIToolbar Class Reference
I create a UIViewController (a custom calendar and its size is 550x440) and when i push a button it must be appear; the problem is that if I use setModalPresentationStyle and setModalTransitionStyle they change size of my view; can I set the size for these presentation?
I find a solution:
[self presentModalViewController:calendar animated:YES];
calendar.view.superview.frame = CGRectMake(0, 0, 200, 200);
Maybe you want to change your design to implement your calendar as a popover:
// Define the size of the calendar view controller for the popover
UIViewController *viewController = [[UIViewController alloc] init];
viewController.contentSizeForViewInPopover = CGSizeMake(550.0f, 440.0f);
viewController.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
// Create the popover
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:navigationController];
// Present the popover from one button
[popoverController presentPopoverFromBarButtonItem:button permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
//release the popover content
[viewController release];
[navigationController release];
